TDA9989

HDMI 1.3a transmitter with CEC support

The TDA9989 can accept any of the following video input modes (see Table 6):

• RGB, with 8-bit for each component

• YCbCr 4:4:4, with 8-bit for each component

• YCbCr 4:2:2 semi-planar, with up to 12-bit for each component (YCbCr)

• YCbCr 4:2:2 ITU656, with up to 12-bit data depth

The TDA9989 can be set to latch data at either rising or falling edge, or both.

7.2.2 Internal assignment

The aim of the video input processor is to internally map the incoming data to the

corresponding mode, which can be handled by the video processing. The internal signal

named VP[23:0] is assigned depending on the input mode as deﬁned below.
